A recent shooting at a family gathering in Stockton, California, on 29 November 2025 highlighted the ongoing debate over gun violence in the United States. As the nation grapples with a historic decline in homicides, the Trump administration has seized the moment to attribute the trend to its hard‑line immigration policies. Experts, however, warn that the claim lacks evidential support and risks distorting the true drivers of falling crime rates.
Administration’s Claim
President Donald Trump told the United Nations General Assembly last week that the country now enjoys “the most secure border in the world, nobody comes in, unless they’re invited. Unless they have permission.” He went on to say, “As a result, last year we achieved the largest drop in violent crime ever recorded.”
Vice‑President JD Vance echoed the sentiment at a rally in Iowa a few days earlier, declaring, “When you get the violent criminals out of your country you see the largest drop in violent crime in the history of the United States of America. Murder rates, because we got the bad guys out.”
The White House has repeatedly reinforced this narrative as midterm elections approach, presenting increased immigration enforcement as the primary explanation for the nation’s falling homicide toll.
What the Data Shows
Researchers point out that the downward trend in homicides began in 2023, during Joe Biden’s presidency, well before the current administration’s immigration crackdown took full effect. Studies examining the relationship between immigration status and violent crime have consistently found no causal link; individuals who are documented or undocumented immigrants do not exhibit higher homicide rates than the native‑born population.
A Guardian analysis published in February revealed that more than three‑quarters of people entering deportation proceedings for the first time had no criminal convictions. Of the 18,400 individuals arrested by ICE between 2025 and June 2026, only 34 were convicted of killing someone. The most common offences among those detained were illegal re‑entry, driving under the influence and a catch‑all “other” category.
Federal authorities themselves acknowledge a gap in knowledge. The Government Accountability Office reported on 28 September that there is no comprehensive, centralised record of the citizenship status of people held in local jails or state prisons, making it impossible to verify any direct impact of deportation on homicide numbers.
Political Anecdotes and Public Perception
Supporters of the administration often cite high‑profile cases to bolster their argument. Trump has repeatedly referenced the 2015 killing of Kate Steinle in San Francisco, noting that the accused was undocumented (though later acquitted), and the 2024 murder of nursing student Laken Riley, whose killer was an undocumented immigrant sentenced to life in prison.
Michael Light, a sociology professor at the University of Wisconsin‑Madison, observed that such stories “should have never been at risk because this person should have never been able to commit these crimes,” but added that the interpretation is “more of a political disagreement than an empirical one.” He cautioned that leaning on anecdotes to shape immigration policy, then claiming those policies alone drove the crime decline, could lead to flawed public‑policy decisions.
Erich Pratt, vice‑president of Gun Owners of America, told the Guardian in a May Instagram video that Americans are “enjoying unprecedented safety” thanks to the Trump administration’s aggressive immigration enforcement. He insisted the drop in homicides “didn’t come from new gun restrictions” but from “a shift in priorities” that targeted violent gang members and ended catch‑release practices for undocumented individuals.
Policy Response and Implications
In response to the ongoing debate, the Department of Justice this week unveiled a $25 million grant programme designed to assist families affected by violence involving undocumented migrants and to fund law‑enforcement initiatives aimed at preventing future deaths.
When approached for evidence supporting a causal link between immigration enforcement and the homicide decline, both the Department of Homeland Security and the White House reiterated their stance that deportations are responsible for the lower crime figures. Neither agency supplied data or research to substantiate the claim.
Why it Matters
Attributing a complex social trend to a single policy lever risks oversimplifying the multifaceted reality of public safety. If policymakers base future legislation on a presumed connection between immigration enforcement and falling homicide rates, they may overlook proven strategies such as community‑based violence prevention, policing reforms and socioeconomic investments that have contributed to the decline. Accurate, evidence‑driven discourse is essential to ensure that resources are directed where they can genuinely reduce harm and protect all communities.
